UNLOADING APPARATUS.

SPECIFICATION forming partof Letters' Paten'tNo. 373,222, dated November15, 1887.

Application filed August 6, 1887.

.To @ZZ whom Vit may concern:

Be it known that I, BAYARD GHALEANT, a citizen of the United States,residingat Kinmundy, in the county of Marion and State of Illinois, haveinvented a new and useful Improvement in YUnloading Apparatuses, ofwhich the following is a specication.

My invention relates to improvements in machines for unloading; and itconsists in a certain novel construction and arrangement of parts, fullyset forth hereinafter, and specifically pointed out in the claims.

In the drawings, Figure 1 is aside view of the device. Fig. 2 is alongitudinal section thereof. Fig. 3 is a central transverse section.

Referring by letter to the drawings, Av designates the framework, whichis built over the pit into which the coal or grain is to bedeposited,and in suitable bearings in the said framework on the level ofthe track along which the cars to be unloaded are moved is mounted theshaft B, carrying the tilting frame or track C. The said tilting frameis provided on the upper side with rails on which to run' the car, andthe under portion is strongly trussed to enable it to bear a greatweight.

D D arey rods or bars passed through or firmly secured to the tiltingframe at each end, and projecting beyond the sides thereof, and to theends'of the said rods are secured the ends of the wire ropes or cablesE,which pass from thence up and over the sheaves F F at the top o'f theframe and near the ends and areattached at the centers to the drums G,which are arranged at the center of the frame. The sheaves FF at eachend ofthe frame are secured to transverse rods f f, and thus they willturn simultaneously, and the drums G G are also secured on a transverserod, g, which is extended outwardly on one side of the frame andprovided on the end with thegear-wheel H.- It will be readily seen thatas the wire rope is secured rigidly at the center to the drum, as thelatter is rotated the rope on one side thereof will be Wound thereon andthe rope on the other side will be unwound,and consequently the tiltingtrack will be inclined, as shown in dotted lines in the drawings.

I Iindicatev sheaves secured to the inner sides of the frame about onthe level of the ground, on which the cables bear when the Serial No.246,306. (No model.)

be attached to the link of the car which is on the track, While to thelower end is attached a rope, chain, or cable, k, which is'fastened atthe other end to a convenient beam under the track. The object of thisdevice is obvious. When the car is run on the track, the holdback isswung down into the position shown in dotted lines to allow the car topass over, after which it is raised and the upper end thereof engagedwith the link on the end of the car. `The chain attached to the lowerend of the lever is now drawn tight and secured, thus preventing the carfrom running off the track when it is tilted in the opposite direction.

L designates a chute which is secured to the tilting track after the caris secured in place thereon, and the said chuteis arranged at the end ofthe car close under the opening Mtherei'n. rlhe said opening in the endof the car is provided on the outside with a swinging door, M', hingedat the upper edge and adapted to swing out as the car is tilted, and itmay be secured in any preferred manner at the lower edge.

.N designates-a vertically-sliding door ar-V ranged on the inside of theopening M and sliding in ways n n, provided therefor at the sides of theopening. To the upper edge of the said door at each end is attached ashort chain, O, which passes up over a transverse bar, l?, arrangedtran'sversely across the end of the car above the opening M and mountedin suitable bearings. The said bar P is provided at the center with ablock, P', provided with aseries of peripheral sockets, in which the endof the lever-bar R isv adapted to be inserted to turn the block, andconsequently the bar is secured thereto. In this way the chains arewound on the ends of the rod and the door N is raised to allow thepassage of the grain or coal.

S designates a small platform arranged on the side of the frame A nearthe top thereof, and in suitable brackets or standards on the saidplatform i s mounted the horizontal shaft IOO T, comprising thedriving-shaft ofthe engine, which is supported on the platform, but notshown in the drawings. The inner end of the horizontal shaft is providedwith a gear-wheel, t, to mesh with the wheel H.

U designates a brake-wheel, also secured to the said shaft and adaptedto be operated upon bya brake to regulate the motion of the shaft, andconsequently of the tilting frame, when the car is being emptied. Thesaid wheel also serves as a balance-wheel to render the motion of theengine steady and pass over centers.

The operation of the invention will be obvious from the above. The cartobe unloaded is run on the tilting track, the holdback or locking-bar Kis attached to the link in the end of the car to prevent the latter fromsliding oft' the track when tilted, and the chute is adjusted andsecured in any preferred manner at the end of the car which is designedt-o be lowered. The sliding door in the end of the car is now raised andeverything is in readiness to unload. The shaft Tis now rotated by thepower, thus turning the gear-wheel H, and .consequently the drums whichare attached to the same shaft as the gear-wheel, and the track istilted and the contents of the car pass through the opening M. When thecar is empty, the engine or power is reversed and the track returned toits horizontal position, when the car is run off, and the device isready to receive another full car.

The device is very simple and easily managed, and if when the car is runon the track it is arranged so as to be balanced it will be seen thatvery little power is necessary to tilt the track.

The operation of the invention being simple and direct, a car may beemptied in a very short time.

rIhe drawings show the device adapted to empty the ear at eitherend-that is, to tilt in either direction; but it will be seen that thismay be alt-ered at will, as there are few cases in which it is ofadvantage to tilt in both directions.

Having thus described my invention, I claim- 1. The combination of thesupporting-frame A, the drum or windlass G in the upper central portionthereof, provided with suitable operating mechanism, the sheaves F nearthe outer ends of said frame, the tilting track supported in said frameand mounted on a pivotal rod, the cable E, connected to thesupporting-frame of the tilting track and, passing over the sheaves F,engaging with the drum G, the anti-frictional sheaves or pulleys I atthe lower outer ends of the track frame, adapted to engage the cable E,the lever-arm K, pivotally mounted at one end of the frame A and adaptedto be secured at its upper end to the coupling link or chain on the endof the car, and the cable 7c, attached to the lower end of said lever tohold it in a vertical position against the action of the coupling linkor chain, substantially as described.

2. In combination with the frame A, having the drum or windlass G, andthe sheaves or pulleys F, arranged in the Lipper portion thereof, asshown and described, the tilting track mounted in said frame A, as setforth, the anti-frictional sheaves or pulleys I at the lower ends ofsaid tilting track, and the cable E, secured to the tilting track andpassing over the pulleys or sheaves I [and F and engaged and operated bythe Windlass or drum G, as set forth, substantially as described.

3. rIhe combination, with the frame A and the tilting track pivotedtherein and adapted to be inclined longitudinally, of the car having theopenings M in the ends, the pivoted outer doors, M', to close the saidopenings, and the sliding inner doors, N, operating in vertical ways,the transverse bars l? above the doors, chains connected to the doorsand adapted to be wound on the said bars, block P on the centers of thebars, provided with peripheral sockets, and the lever R, to insert inone of the sockets to turn the block, substantially as and for thepurpose specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

BAYARD CHALFANT.
